Ah, good work, very sneaky! We won't tell the wife. I can obviously see your plan to eventually annex Bedroom 3 into the garage by simply knocking out a wall. Let me guess, you'll call it a "storage room" and pile some boxes right by the door, implying the room is full. Then you make the hole in the garage and build a "door" from cardboard boxes, so only you have access to the hidden free space in the former bedroom.
Very good, I like it.
